Abstract

"PROCESSO PARA CONTROLAR UM SISTEMA INTEGRADO DE UNIDADE DE SEPARAçãO CRIOGêNICA DE AR/TUBINA A GáS E SISTEMA PARA CONTROLAR UMA INTEGRAçãO DE UNIDADE DE SEPARAçãO CRIOGêNICA DE AR/TURBINA A GáS". Um processo para controlar um sistema integrado de unidade de separação criogênica de ar (ASU) / turbina a gás que mantém a potência de pico de saída apesar das variações da temperatura ambiente. A taxa de fluxo de ar para a ASU de uma fonte de ar suplementar e de um compressor de turbina é ajustada para compensar as mudanças na temperatura ambiente e para manter o fluxo de ar para a ASU em um nível que garanta a produção de produto; uma corrente de combustível é controlada para manter a produção gasosa de um combustor em uma máxima temperatura prática e uma vazão de nitrogênio residual e de combustível alimentados no combustor é mantida substancialmente constante.
